Prognosis
It is a serious medical disorder and the mortality rate can be as high as 30%. The high mortality rate is likely a measure that this syndrome is seen in critically ill patients, rather than this syndrome being in itself lethal, although it can also present in otherwise healthy individuals (especially if the disorder was induced by pharmocologic agents). Drug induced megacolon (i.e. from Clozapine) has been associated with mortality as high as 27.5%.
